print two dimensional list

Question

I have a list, in which is another list and I want to doc.write(a)

a = [[1, 2, \"hello\"],
     [3, 5, \"hi There\"],
     [5,7,\"I don\'t know\"]]
         


        

Answer 1

What about using itertools?

from itertools import chain
doc.write(''.join(map(str, chain(a))))

Alternatively:

doc.write(''.join(str(i) for sub_list in a for i in sub_list))

You suggested a using a for loop. You could indeed do this, although the options above are probably better.

new_a = []
for sub_list in a:
    for i in sublist:
        new_a.append(str(i))
doc.write(''.join(new_a))

This is basically the previous option, but unrolled.

Unless you want to just write the first list, in which case you could do this:

doc.write(''.join(map(str, a[0])))
